Be it known that'I, BENJAMIN BRITTEN, of Galena, in the oounty'oif Jo Daviess, and State of Illinois, have invented'a new and improved Window-Sash Supporter; and I do hereby declare that' the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same. reference being had to the accompanying drawings, forming'part of `this specification, in whiehv igure 1 is a view of the inside of a window frame, showing the supporters attached for both the upper and lower sashes.-

Figure 2 is an edge view of the sash.

Figure 3 is a front view of the same.

Figure 4 is a. view ot' the interior of the sash supporter.

'Figure 5 is a face or outside view lof the same.

Similar letters of" reference indicate like parts.

Thisinvention relates 'to au improved device for supporting window sashes in the frame, and consists in a combination of' two levers with a spring, attached to a metal case which is let into the window frame horizon tally, one supporter for each sash', The supporter for the upper sash has its thumb-piece for depressing the catch within the seat of the lower sash, lying ilat and iiush with the frame, so that it presents no obstacle to .the movement of the sash up and down. A very slight pressure upon the flat thumb-piece releases the catc'n s nd permits the sash to be lowered, whilel a spring holds the catch in place in notches on the edge of the sash C to keep it up. v i

In fig. 1, A represents one side ot' a window frame, having the supporters B fastened with screws to it for both the upper and lower sashcsf The supporter has n rectangulur metal case or frame, which may be open at the ends and bottom, and is let into a. suitable cavity in the wood of the frame, as shown in iig. 4, thc upper side being ilush with the surface. Within the case of the supporter are' piroted to the sides two levers, n, b. The thumb-piece c is placed on the end ofthe short arm ofthe lever a and tlievcatch d, which projects through the upper eide of the case, is on the end ofthe long arm of'the leverb'. The levers are so arranged that when the thumb-piece c is depressed, Ithe long arm ofthe lever'a lifts the short arm of the lever b, and throws the lcatch d back in the case to release the window sash. By this arrangement the catch moves four times as fur as the thumb-piece, which, therefore, requires a very slight ,pressure to operate the supporter. The catch dis thrown out by a spring, e, which may be made either lint, as represented, or spiral, to keep the sash up. The

'at thumb-piece c not only allows the sash to more freely over it, butit is much neater than a button or knob',

commonly used for the purpose, as shown for comparison. It may be painted over with the woodwork so as hardly to he seen, and is entirely out of the way.

Having. described ny invention, I claim as new, and desire to securch'y Letters Patent- The arrangement of the compound levers a b, comhinedwith vthe flat thumb-piece c and thc spring e, when applied to a sash supporter in the manner herein described,

BENJAMIN BRI'ITEN.
